line renderer to draw multiple lines
I want to draw three separate lines with line renderer, but I can only see one when I run the program. How can I make all of them appear? Thanks!
enter code here` using System.Collections; using System.Collections.Generic; using UnityEngine;
public class Keep_dist : MonoBehaviour { public GameObject eye; public GameObject Pikachu; public Vector3 a; public Vector3 b; public Transform obj1_s; public Transform obj1_e; public LineRenderer line1; public Transform obj2_s; public Transform obj2_e; public LineRenderer line2; public Transform obj3_s; public Transform obj3_e; public LineRenderer line3; // Start is called before the first frame update void Start() { line1 = eye.GetComponent(); line2 = eye.GetComponent(); line3 = eye.GetComponent(); }
public void MoveGameObject()
{
Pikachu.transform.position = b;
}
// Update is called once per frame
void FixedUpdate()
{
a = eye.transform.position;
b = Pikachu.transform.position;
b.x = a.x + 1;
b.y = a.y;
b.z = a.z - 3;
MoveGameObject();
//print(a.ToString());
//print(b.ToString());
line1.SetPosition(0, obj1_s.position);
line1.SetPosition(1, obj1_e.position);
line2.SetPosition(0, obj2_s.position);
line2.SetPosition(1, obj2_e.position);
line3.SetPosition(0, obj3_s.position);
line3.SetPosition(1, obj3_e.position);
}
}
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class $$anonymous$$eep_dist : $$anonymous$$onoBehaviour
{
public GameObject eye;
public GameObject Pikachu;
public Vector3 a;
public Vector3 b;
public Transform obj1_s;
public Transform obj1_e;
public LineRenderer line1;
public Transform obj2_s;
public Transform obj2_e;
public LineRenderer line2;
public Transform obj3_s;
public Transform obj3_e;
public LineRenderer line3;
// Start is called before the first frame update
void Start()
{
line1 = eye.GetComponent<LineRenderer>();
line2 = eye.GetComponent<LineRenderer>();
line3 = eye.GetComponent<LineRenderer>();
}
public void $$anonymous$$oveGameObject()
{
Pikachu.transform.position = b;
}
// Update is called once per frame
void FixedUpdate()
{
a = eye.transform.position;
b = Pikachu.transform.position;
b.x = a.x + 1;
b.y = a.y;
b.z = a.z - 3;
$$anonymous$$oveGameObject();
//print(a.ToString());
//print(b.ToString());
line1.SetPosition(0, obj1_s.position);
line1.SetPosition(1, obj1_e.position);
line2.SetPosition(0, obj2_s.position);
line2.SetPosition(1, obj2_e.position);
line3.SetPosition(0, obj3_s.position);
line3.SetPosition(1, obj3_e.position);
}
}
All those eye.GetComponent() lines are returning the same LineRenderer. You should either assign those manually (better option, but remember to remove the assignment from Start) or use GetComponents which will give you all LineRenderers from the object.
Also in case this is your problem: one LineRenderer can only draw one line! It can be a curve, but it's a singular line with only two ends
Thank you, I fixed my problem. Really appreciate it.
